Punch Cups by Diana
Punch cups should match the sort of punch they hold and the event that they are being used for.
Although they are many ways to demonstrate this, I decided to:
* Correlate the punch with the shape of the cup
* Relate the width of the rim to the amount of activity happening at a particular party.
Design Drivers
* Kool-Aid © served at a 6 year old's birthday party - shape resembles the Kool-Aid © mascot, rim width prevents spilling
* Lime Sherbet served at a traditional Southern party with limited seating - shape resembles a traditional Southern punch cup (which resembles a tea cup), rim width prevents spilling
* Spiked Punch drunk in a mosh pit - shape resembles the stem of a mushroom cloud (thanks Scott, for the analogy), rim width prevents spilling

Lessons Learned
- If you change parameters in a certain order, the object may seem impossible, but it is probably just a result of inadequate design.
- Always have a spare file of your basic design so that when you start implementing more completed elements, you don’t risk having to start from scratch.
- My CAD file dictates the shape of the cup with X and Y coordinates of the cup and the curve of the cup. With more refinement, the CAD would be able to internally change these coordinates and the shape could be changed with a more general command.
Discussion
Could you include some images of the configurations?
Well presentation with the function of your different design results. I do not understand the geometrical forms of your symbols in the logic diagram, but it is probably me as a reader the is the reason for that. The presenting of the design drivers was clear and easy to understand. Well done!
Diana, this project had some great results - I feel especially tied to the results as I watched you stress over CAD for quite a few hours. I'm still struggling to master the logic diagramming process but must say that I found yours easy and manageable to follow.
You have some great lessons learned too. To be honest, I didn't keep back up files while I was going and that was pretty unwise. I will definitely do it next time after reading your lessons learned and seeing some of the trouble you were having. It also might be a blessing to have back up files because then you have other templates to play with as you move forward - you can try different things and see all the permutations you could end up with from the same starting point.
